This study aims to evaluate the preventive effect of (-)-epigallocatechin-gallate (EGCG) on lipid peroxides, enzymatic and non-enzymatic antioxidants and histopathological findings in isoproterenol (ISO)-induced rats. Myocardial infarction (MI) is induced in rats by subcutaneous injection of ISO
This article reports data on the preventive effect of (-)epigallocatechin gallate (EGCG) on lipid metabolism and lipoproteins in isoproterenol (ISO)-induced myocardial infarction (MI) in Wistar rats. The rats were induced MI by ISO (100 mg/kg) at an interval of 24 h for 2 days. EGCG (30 mg/kg) was
Polyphenol (-)-epigallocatechin gallate (EGCG), the most abundant catechin of green tea, appears to attenuate myocardial ischemia/reperfusion injury. We investigated the involvement of ATP-sensitive potassium (K(ATP)) channels in EGCG-induced cardioprotection. Isolated rat hearts were subjected to
Ischemia-derived exosomes can restrict excessive autophagy by transferring microRNA-30a (miR30a) to cells. Reports have confirmed that epigallocatechin gallate (EGCG) alleviates acute myocardial infarction (AMI) by regulating autophagy; however, research evaluating the communication BACKGROUND
This experiment was performed to determine the effect of polyphenolic (-)-epigallocatechin (EGCG), the most abundant catechin of green tea, given at reperfusion period.
METHODS
Isolated rat hearts were subjected to 30 min of regional ischemia and 2 h of reperfusion. Green tea extract (GT)
Altered mitochondrial function and free radical-mediated tissue damage have been suggested as important pathological events in isoproterenol (ISO)-induced cardiotoxicity. This study was undertaken to know the preventive effect of (-)epigallocatechin-gallate (EGCG) on mitochondrial damage in
BACKGROUND
The activation of guanine nucleotide binding protein-coupled receptors, such as adenosine receptor (ADR) and opioid receptor (OPR), protects the heart against ischemia and reperfusion injury. We hypothesized that ADR or OPR might be involved in polyphenol (-)-epigallocatechin gallate
We evaluated the efficacy of epigallocatechin gallate (EGCG) for improving function in rats with transient middle cerebral artery occlusion (MCAO). Three procedures underwent for each groups; MCAO and EGCG treatment, MCAO without treatment (MCAO control), and sham operation. Function was evaluated
BACKGROUND
Ischemic stroke is the leading cause of death and disability worldwide. To date, recombinant tissue plasminogen activator (rt-PA) remains the only safe and effective pharmaceutical treatment for brain ischemia, but delayed rt-PA administration leads to hyperperfusion, which severely
This study examined the neuroprotective effects and possible hepatotoxicity of (-)-epigallocatechin gallate (EGCG) in a rat model of transient focal cerebral ischemia. Male Sprague-Dawley rats (265-295 g) were treated with either 50 mg kg(-1) of EGCG or saline, i.p., immediately post-ischemia and
(-)-Epigallocatechin gallate (EGCG) is the main polyphenol component of green tea (leaves of the Camellia sinensis plant). EGCG has been reported to protect human brain microvascular endothelial cells (HBMECs) against injury in several models. However, the exact mechanism is still unclear. In the
Green tea polyphenol (-)-epigallocatechin gallate (EGCG) has been reported to reduce neuronal damage after cerebral ischemic insult. EGCG is known to reduce matrix metalloproteinase (MMP) activity. MMP can play an important role in the pathophysiology of neurological disorders including cerebral
Epigallocatechin gallate (EGCG) has established protective actions against myocardial ischemia/reperfusion (I/R) injury by regulating autophagy. However, little is known about the mechanisms of EGCG in posttranscriptional regulation in the process of cardioprotection. Here we studied MicroRNA 145 (miR-145) is a critical modulator of cardiovascular diseases. The downregulation of myocardial miR-145 is followed by an increase in disabled-2 (Dab2) expression in cardiomyocytes. (-)-epigallocatechin gallate (EGCG) is a flavonoid that has been evaluated extensively due to its diverse
Epigallocatechin gallate (EGCG), a major constituent of green tea, is a potent free radical scavenger. The purpose of this study was to verify whether EGCG reduces focal ischemia/reperfusion-induced brain injury in a rat model. Male Sprague-Dawley rats were anesthetized with chloral hydrate (400
